Perhaps this and other pmu-chain* tests are failing due to lack of
commits from
https://lore.kernel.org/r/20221113163832.3154370-5-maz@xxxxxxxxxx in the
5.15 kernels (and these landed upstream in v6.2).

Title:
  pmu-chain-promotion from ubuntu_kvm_unit_tests fails on B/F/H/J arm64

Status in ubuntu-kernel-tests:
  New

Bug description:
  With kvm-unit-test repo updated to e11a0e2f88 ("s390x: Fix integer
  literal in skey.c"), there are 6 failures reported in this test on
  ARM64 now.

  1: pmu-chain-promotion: odd counter did not increment on overflow if disabled
  2: pmu-chain-promotion: should have triggered an overflow on #0
  3: pmu-chain-promotion: CHAIN counter #1 shouldn.t have incremented
  4: pmu-chain-promotion: CHAIN counter enabled: CHAIN counter was incremented and overflow
  5: pmu-chain-promotion: 32b->64b: CHAIN counter incremented and overflow
  6: pmu-chain-promotion: overflow is expected on counter 0
